Observation 31945: Amanita “sp-C20”
When: 2010-01-09
No herbarium specimen
0 Sequences

the first fruit body came in entirely white, with spikey warts that were not readily removed. by the next day, it had reddened after handling, then turned more of a reddish brown. the annulus is decidedly membranous, and like a novinupta, there is no volval remnant at the base. this same species, whatever it is, also came into the MSSF Fungus Fair in early December, where it was misidentified as a “cokeri”.

no herbarium specimen (damn persishable amanitas) but I will ask the folks in SC to keep an eye out and try and collect more. This looks to be a good year for it.

I am attempting to get more material.

Ah, yes, that one…

Debbie said on a posting under the older observation that she was drying a specimen. Debbie, is that one of the one’s you sent here?


I saw it

I saw this one, its not novinupta. Clearly a Lepidella. There was no red staining on it when I saw it, but there is red staining in these pictures. Interesting how it fades after a couple days. I guess its the same species as this observation.

Well, I guess we all have to start carrying around ferrous sulfate…

I am not really sure where this guy belongs, and I’m not pushing for novinupta. A number of thoughts came to mind include lepidellas. But I really don’t want to guess when I know so little.


I have never collected it…

just seen it post collection.

And always in a situation where I can’t trace back who collected it or where (ie the jumble of a Fungus Fair, w/out good collection data).

I have tried very hard to make this into novinupta myself, but it really doesn’t fit, quite.

Well, I will be rootin’ for the folks in Santa Cruz to find this again.

Greg Wright wrote that there was a species like Amanita novinupta in many ways but strongly reactive to ferrous sulfate solution (or crystal, as some prefer). Do you know anything about the habitat of this one?
